Title: Resistance measuring device
Inventor: SHIMADA KOICHI
IPC: G01R27/08
Filed: 1985-08-16
Abstract: PURPOSE:To make it possible to measure a high resistance body connected to first and second switches, by connecting a plurality of series circuits of first and second switches comprising a semiconductor in parallel and further connecting said circuits to both terminals of a constant voltage source through a current detecting resistor. CONSTITUTION:At the time of the measurement of high resistance, a high voltage resistant diode 39 is connected to a current supply transistor Tr 26 in series so as to withstand the high voltage of a constant voltage source 13. A current detecting Tr 28 is also formed of a high voltage resistant element and, in order to bring the leak current to a Tr driving circuit to zero, photoresistors are used as Tr 26, 28 and connected to the driving circuit by a photocoupler. At the time of measurement, switch 34, 35, 33 are turned ON and a switch 31 is turned OFF. In this state, the supply voltage of the constant voltage source 13 is monitored from the output of an amplifier 37 and, for example, the minute current flowing to the high resistance body to be measured connected to measuring terminals 31, 32 is detected on the basis of the output of an amplifier 16 or 38 and the resistance value of the high resistance body is measured.

Abstract: PROBLEM TO BE SOLVED: To provide an operating method of a blast furnace, with which ventilation in the furnace is kept to good condition without using coke having good quality and the stable operation is executed even at the time of blowing a large quantity of pulverized fine coal. SOLUTION: Solution-loss reaction carbon content at each position of the center part 1 in the furnace, the furnace wall part 3 and the intermediate part 2 (the intermediate part between the center part and the furnace wall part) is calculated by using a computer 10 from the measured values of gas composition and gas flowing speed at each position obtd. with a shifting sonde 8 disposed at the furnace top part. The position developing the deterioration of coke caused by the solution-loss reaction based on the variations of these calculated values is estimated and the grain size distribution of the coke charged from the furnace top in the radial direction in the furnace is adjusted so that the grain diameter of coke at this position becomes larger than the grain diameter of coke at the other position.

Title: Production of optical semiconductor device
Inventor: TAKAHASHI AKIRA
IPC: G02F3/00
Filed: 1993-07-21
Abstract: PURPOSE:To provide an optical semiconductor device capable of extremely shortening the life of carriers excited by irradiation with control light by growing a quantum well layer in a specific temp. range. CONSTITUTION:The quantum well layer grown at a temp. lower than an ordinary growth temp., i.e., 150 to 400 deg.C is used as an optical nonlinear material. A p type element or Be is added as a dopant into the quantum well layer during the low-temp. growth of the layer and further, the layer is subjected to an annealing treatment after the low-temp. growth. Recombination centers are considered to be formed at a deep level if the growth is conducted at 150 to 400 deg.C by lowering the temp. in such a manner and, therefore, the life of the carriers is speeded up to about 100 picoseconds. The carriers decrease down to about 1 picosecond if the p type element or Be is introduced into the layer during the growth. Further, the doped acceptors are activated to compensate the carriers generated during the low-temp. growth of the quantum well layer after the growth is subjected to the annealing treatment at about 500 deg.C and, therefore, the extremely high-resistance quantum well layer is obtd.

Abstract: PURPOSE: To make it possible to easily form the unmagnified image of an object in a position where an observer is able to touch an opaque or translucent panel by arranging many reflection elements having reflection surfaces orthogonal with a panel surface on the panel. CONSTITUTION: This optical imaging device is constituted by arranging the many reflection elements 12 having the reflection surfaces 13 on the opaque panel 11. The reflection elements 12 consist of columns made of transparent plastic or glass and are formed by coating the outer flanks of these columns with metal, such as aluminum, to a mirror finished surface form in such a manner that the whole of the inner flanks of the columns constitute the reflection surface to reflect incident scattering light. The reflection surfaces of the many reflection elements 12 are arranged within the panel 11 in such a manner that the reflection surfaces intersect orthogonally with the plane of the panel 11 at nearly equal intervals and that the scale of integration is nearly maximized.  A surplus scattered light may be not reflected by forming the reflection surface only in a specific range of the inner flanks of the columns in the case the position of the objects is fixed.

Title: Controlling method for axial blower capacity
Inventor: TOMINAGA TETSUO
IPC: F04D27/00
Filed: 1988-07-22
Abstract: PURPOSE:To attain the total air capacity and blast pressure of very wide range by means of high efficiency and low power by combining a change in number of rotations with a change in angle for fixing a stator blade so as to change them in interlocking with each other under optimum conditions. CONSTITUTION:An angle for fixing a stator blade  theta which satisfies air capacity Q at an operating point is obtained. And the number of rotations N is obtained from a functional relation with the angle for fixing a stator blade  theta. Then the angle for fixing a stator blade  theta and the number of rotations N are defined as the number of rotations and an angle for fixing a stator blade respectively concerning air capacity at the next operating point. Consequently, the air capacity and blast pressure of the axial blower concerned can be changed widely rather than those under an individual control. In particular, if the interlocking combination of the number of rotations N with the angle for fixing a stator  theta is selected under optimum conditions, as a favorable internal flow rather than that under a conventional individual control is generated when air passes through an impeller, the adiabatic compression efficiency of the blower can be improved so that its low-consumption power operation can be realized.
